Abstract

Abstract: This paper briefly introduces the basic principle and experimental procedure of the determination of oil-bearing formation damage by long core experiment, analyzes the method of the determination of formation invasion and damage depth by the long core experiment, and points out, through the analysis of the experimental data, that the invasion depth of mud filtrate is greater than the damage depth of mud filtrate in formation, and that the damage of filtrate to formatin is less than that of mud particles.

Key words: Core, Experiment, Damage, Formation
